Application filed September 18, 1918. Serial No. #5 1,564.

To all whom it may concern:

Be it known that 1, WILLIAM DUNNELL, a citizen of the United States,residin at Detroit, in the county of Wayne and tate of Michigan, haveinvented certain new and useful Improvements in Guspidors, of which thefollowing is aspecification, reference being had to the accompanyingdrawings.

This invention relates to certain improvements in cuspidors, and it isan object of the invention to provide a device of this general characterwith novel and improved means whereby the same is rendered sanitary.

Another object of the invention is to provide a device of this generalcharacter with which coacts a lid or cover member which is normally in aclosed position, and wherein the bowl of the cuspidor is flushed whenthe lid or cover member is in open position.

- An additional object of the invention is to provide'a device of thisgeneral character including a normally closed lid or cover membertogether with novel and improved means whereby said lid or cover membermay be move into open position with a minimum of physical effort.

the details of construction and in the combination and arrangement 'ofthe several parts of my improved cuspidor whereby certain importantadvantages are attained and the device rendered simpler, less expensiveand otherwise more convenient and advantageous for use, as will behereinafter'more fully set 'forth.

The novel features of my invention will hereinafter be definitelyclaimed.

. In order that my invention may be the I will now proceed to describethe same with reference to the-accompanying drawings, wherein:

Figure l isa fragmentary view partly in side elevation and partly insection illustrating a cuspidor constructed in accordance with anembodiment of my invention, the line of section being taken at one sideof the bowl of the cuspidor proper; 1

Fig. 2 is a fragmentary view in vertical section taken through thecuspidor proper;

Fig. 3 is an enlarged fragmentary view partly in section and partly inelevation, illustrating the connection between the operating rod and thevalve interposed in the supply pipe as herein disclosed together with ameans for automatically returning the rod to its normal position; and vFig. 4 is a fragmentary view in top plan illustrating the connectionbetween the flexible member and the lid or cover member as hereinembodied.

As disclosed in the accompanying drawings, F denotes a flooring havingproduced therethrough an opening 1.

B denotes the bowl of a cuspidor proper and which is herein disclosed inthe form 0 an inverted cone, and said bowl is suitably supported by theunder face of the flooring F with the upper or larger face of the bowl Bsurrounding and substantially defining the opening 1.

The upper or larger end portion of the bowl B is provided with aninwardly directed flange or lip 2, and arranged within said bowl B andunderlying the flange or lip 2 is a flush pipe 3 adapted to dischargedownwardly upon the inner wall of the bowl B to effect a thoroughcleansing thereof. The flush pipe 3 is in communication with a pipe 4leading from a suitable source of water supply, preferably under mainpressure, although this is not a particular feature of my invention, asthe water supply may be of any character to assure the proper dischargethrough the flush pipe 3. Interposed in the pipe 4 exteriorly of thebowl B is a valve 5 provided with an operating member 6. which willhereinafter be more particularly referred to. v

The lower or apex portion of the bowl B is provided with a restricteddischarge opening 7 in communication with a trap 8, and

which trap 8 is continued by a waste pipe 9.

The trap 8 as particularly illustrated in Fig. 2 is of such a characteras to assure a liquid seal for the lower end portion of the bowl B. Thepurposes and advantages of the liquid seal are believed to be clearlyapparent to those skilled in the art to which my present inventionappcrtains. Coacting with the opening 1 is a lid or cover member 10hingedly connected as at 11 with the flooring F. and said lid or covermember 10 is mounted for swinging move mentin a vertical plane. Theflooring F to one side of the opening 1 and adjacent the hingedconnection'll is provided with an member.

opening. 12 through which is directed a downwardly inclined arm llsuitably secu'red to a side edge or face of the lid or cover member 10.The arm 14 is offset outwardly of the lid or cover member 10 as isparticularly illustrated in Fig. 4.

Suitably afiixed to the lower or free end portion 14 is a chain 15 orother flexible This chain or member 15 is disposed inwardly anddownwardly in a direction toward the bowl B and is disposed over a guidepulley i116 suitably mounted upon a support of any convenient character,such as one of the supporting girdles or beams G for the flooring F.

The inner end portion of the chain or flexible member 15 is secured tothe upper end portion of the outwardly and downwardly inclined lever orarm 17. The lower 'end portion of this lever or arm 17 is pivotallyconnected as at 18 to the waste pipe 9 or other suitable support, and iscapable of swinging movement in a vertical plane so that upon downwardswinging movement of the lever or arm 17 the lid dr cover member 10,through the medium of the chain or other flexible member 15 and the arm14 will be swung upwardly into an open position.

19 denotes a rod mounted for rectilinear movement in a vertical path andwhich is pivotally connected, as at 20, to the lever or arm 17 at apoint inwardly of but'preferably in close proximity to the pivotalconnection 19. The upper or opposite end portion of the rod .19 extendsthrough the flooring F and terminates thereabove, and as described inthe present embodiment of my invention the upper end portion of said rod19 has secured thereto a removable cap or pedal 21.

By, pressin I end of the r0 19 by a foot, it will be obvious that thedesired movement may be imparted to the lever or arm 17 to effect theupward swinging movement of the lid or cover mem ber 10.

The lid or cover member 10 is normally maintained closed, and in orderto permit the return of the lid or cover member 10 to its normalposition, I find it of advantage to employ a coil spring 22 encirclingthe rod 19 and secured at its lower end to the rod 19 and at itsopposite endto the flooring F. The spring 22 as herein disclosed is of aretractile type and possesses suflicient tension toelevate the rod 19when relieved of pressure so that the lid or cover member 10 will befree to drop by gravity to its closed or normal position.

Extending laterally from the rod 19 is a use into the trap 8 and wastepipe 9 whi downwardly upon, the upper operating member 6 of the valve 5extends so that when the rod 19 is forced downwardly to raise the lid orcover member 10, the valve 5 will be moved into open position so thatthe requisite flow may be had throughout the pipe 3 to properly flushthe bowl B. When the rod 19 is returned under the influence of thespring 22, it will be self-evident that the valve 5.will be moved intoclosed position so that flushing of the bowl B will not occur when thelid or cover'member 10 is in its closed or normal position.

I find my improved cuspidor to be of particular advantage in use inconnection with persons suffering with tuberculosis or other diseaseswhereby contagion may be spread through ex'pectoration although it is tobe noted that my improved cuspidor entirely eliminates the emanation ofthe disagreeable sect the lower portion of the bowl B with a I screeninelement 24, and which element is herein isclosed as comprising a sheetof reticulated fabric. This element 24: serves to prevent the passage oftrash or other rei would otherwise have a tendency to hinder orobstructthe flow therethrough.

By having the cap or pedal 21 removable, an extension may be readilyengaged with the upper portion of the rod 18 so that a person in areclining position, such as a atient occupying a bed may convenientlyepress the rod 18 through the medium of such extension when suchpersonor patient desires to expcctbrate within the bowlB;

From the foregoing description, it is thought to be obvious that acuspidor constructed in accordance with my invention is particularlywell adapted for use by reason of the convenience and facility withwhich it may be assembled and operated, and it will also be obviousthatmy invention issusceptible of some change and modification Withoutdepartin from the principles and spirit thereof, an for this reason I donot wish to be understood as limiting myself to the precise arrangementand formation of the several parts herein shown in "carrying out myinvention in practice except as here-' inafter claimed.

I claim: i l

In combination with a flooring having an opening therethrough, a 'bowlsuspended from the flooring and surrounding the ope.n-' ing, saidflooring being provided with a second opening. a cover hinged to thefioorin and coacting with the first named opening, an arm secured to thecover and extending through the second named opening in the flooring, alever supported for rocking move:-

ment below the flooring, a flexible connection between the lever and thearm whereby movement of the lever in one direction moves the cover intoopen position, an endwise movable member-disposed through the flooringand, engaged withthe lever whereby downward: movelhent of the rod swingsthe lever in a direction to elevate the cover, said covering moving byravity into closed position when the rod 1s relieved of pressure.

In testimon whereof I hereunto afiix my signature in t e presence of twowitnesses.

WILLIAM DUNNELL.
